BALING-PRESS.

Specification of Letters Patent.

Application filed. March 26, 1910.

Patented Feb. 14, 1911.

Serial No. 551,779.

To all whom, it may concern:

Be it known that I, GUSTAF TV. PEARSON, citizen of the United States, residing at Fresno, in the county of Fresno and State of California, have invented new and useful Inun'ownnents in Bailing-Presses, of which the following is a specification.

This invention relates to balingn'esscs oi the horizontal. or continuous type, such as are usually operated by animal power.

It is the object of this invention to provide a baling-press in which the hay, straw, or other materials to be baled, may be automatically delivered to the teed chamber from the ground level, and in which the feed table o'l common practice is dispensed with, thereby enabling one man to do the work of two, when baling from the ground or buck-rake, with less etlort than where the feed table is employed.

A further object is to provide a balingpress in which the pressing plunger is given a long stroke so as to increase the feeding capacity, and having means by which the force of the plunger is nnit'orn'ily increased during the pressing operation, so as to equalize the work of the draft animals.

Another object of the invention is to provide a press by means of which hay and the like can be COII'IPLOSSGd into compact bales suitable for export shipping.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which-- Figure 1 is a plan view of the power end of the press, showing the pitman and parts in an intermediate position. Fig. 2 is an end view of same. Fig. 3 is a plan View with the pitman near its :torwardmost position. Fig. 4t is a plan view of the feed chamber and press. Flg. is an end View ot same.

In the drawings, A represents the frame- Work of my baling-press, near one end of which is mounted a bed-plate 2. A vertical shaft 3 is jonrnaled in the bed-plate 2 and is retained in alinement by a suitable journalbox 4 near its upper end. The shaft 3 is adapted to be rotated in its bearings in any desired manner, but this rotation is preterably accomplished by securely mounting a sweep 5 on the upper end of the shaft 3, to

the outer end of which are hitched suitable dra'lt animals. in the usual manner.

Av cross-head (l is rigidly secured to the shaft 3 at a point beneath the journal-box at, and has rollers 7 7 mounted on the outer ends thereol, the rollers 77 extending beneath the cross-head (3, as shown in Fig.2, and adapted to engage and act upon a toggle .link 8. The link 8 is pivotally mounted at 9 upon a standard formed on the bed-plate 2, and extends below the path of travel of the cross-head t'. An upwardly projecting, curved portion or cam 10 is formed on the link 8, and is so disposed as to be engaged by the rollers 7 7 to move the link 8 forward as the cross-head (3 revolves in the direction of the arrows. the cam 10 being of such length as to be released from the rollers T-T when the link has reached its 'tor\\"ardmost position, shown in Fig. 3. The outer end of the link 8 is pivotally connected to a pushbeam ll which extends to a considerable length and is provided with a pin 12 at its outer extremity which is adapted to slide in a slot 13 formed on the pitman or plunger 1st.

The plunger 141: is preferably constructed of heavy pipe and is provided at one end with a rectangular head 15, as shown in Fig. l, which is supymrted and reciprocal in the prcssi ug chamber or press-box, and the opposite end is slidably supported upon the bedplate Normally the plunger l t, push-beam 11 and link 8 occupy the position shown in dotted lines in Fig. 1,. with the pin 12 contact-- ing the outer end of the slot 13. 11011 the roller 7 or 7 engages the cam 10 and moves the link 8 iloiwvard. the push-beam 11 travels therewith and pushes the plunger 14: forward into the baling or press-box a distance governed by the length of the link 8.

The forward stroke of the plunger 11.,just described, is insutlicient to thoroughly compress the materials in the baler, especially for export, and to increase the length of the plunger stroke through the cross head (3 and link 8 would decrease the leverage and require more power to rotate the shaft 1), which would impose a strain upon the draft animals near the end of the con'ipression stroke, and possibly stall the machine at that point. If the plunger Ll was to stop its forward movement at this point, the sudden release of the cross-head (3 from the link 8 would cause the strain on the draft animals to be quickly relieved, thereby making their work uneven and difficult. As a means of increasing the stroke of the plunger, increasing the leverage on the cross-heads and equalizing the work of the draft animals, I employ an auxiliary cross-head 16 which is secured to the shaft 3 beneath the cross-head 6, and is provided with friction rollers l717 which are on a plane with the plunger let. The cross-head 16 is disposed at an angle in relation to the cross-head 6, and is of such length as to engage the end of the plunger 14L and move the latter forward, as will now be described.

vVhen the shaft 3 revolves, and carries the cross-heads 6-16 therewith, the former cross-head moves the plunger 1% forward through the link 8, as before mentioned, and when the intermediate position shown in Fig. 1 is reached, the roller 17 on the cross-head l6 bears againstthe side of the plunger 14: and shoves the end resting upon the bedplate 2 to one side, the plunger 1ft simultaneously continuing on its forward movement. WVhen the plunger has nearly reached the limit of its stroke as caused by the crosshead 6, the crosshead 16 is then in position to engage the end of the plunger and is caused to do so by reason of the plunger 14L being shoved in front of the roller by the following mechanism: A downwardly inclined plate 18 is mounted on the underside of the link 8 and projects forward thereof a suflicient distance to contact and bear against an arm 19 when the link is near its forwardmost position. This arm 19 is pivoted at 20 to the frame A and has a platespring 21 on its outer end which bears against the side of the plunger 14L As the link 8 nears its forward stroke, the plate 18 contacts the lever 19 which in turn bears against the plunger 1 1 and forces it over in the path of the cross-head 16. At the same time a projection 22 on the plunger 141 is contacted by the push-beam 11, which also aids to throw the plunger 14- in line with the cross-head 16. A friction roller 23 mounted on the bed-plate 2 limits the sidewise movement of the plunger 1a, and in conjunction with the projection -22 tends to retain the plunger in alinement. Continued rotation of the short cross-head 16 causes the plun ger 14 to complete its forward stroke, which stroke continues until the rollers 17l7 pass the end of the plunger, the slot 13 permitting the plunger to move irrespective of the beam 11. A curved plate 2 1 is mounted in the end of the plunger against which the rollers 1717 bear.

As a means of restoring the plunger 14. and the cam link 8 to their normal position after the completion of a forward stroke. a curved lever-arm 25 is pivoted at 26 to the bed-plate and has a cable 26 secured to its outer end, theopposite end of the cable 26 being suit-ably secured to the plunger it near its forward end, as shown in Fig. at. A stiff spiral spring 27 is interposed between the lever-arm 25 and cable 26 for a purpose later described.

As the cross-head 16 leaves the end of the plunger 14L, the lever 25 is in the position shown in Fig. 3, whereupon the roller 7 or 7 on the cross-head 6 engages the curved lever 25 and carries it backward to the position shown in dotted lines in Fig. 1, which, through the cable 26, returns the plunger to its normal position, the push-beam 11 and link 8 being carried back therewith. A portion of the lever-arm 25 is cut away to permit of the rollers 7 7 leaving at the proper time, so as to release the lever-arm and cable to permit of another stroke of the plunger.

The backward movement of the plunger is retarded by means of a friction brake, which is constructed as follows: The arm 19 is linked at 28 to a lever-rod 29 pivoted at 30 to the frame A. An adjustable weight 31 is mounted on the outer end of the lever 29, and a wooden block is secured to the under side of the lever and is adapted to slide upon the portion A of the frame.

The action of the brake is as follows: As the plunger 1% comes back 011 its rearward stroke, it strikes the spring-plate 21 on the lever 19 and forces the latter back, and shoving the lever 29 and friction block 32 therewith. The friction of the block 32 on the frame A is sufficient to cause the lever 19 to press against the plunger with suiiicient resistance to brake its backward movement. A suitable stop is provided in the balingbox against which the plunger-head 15 is brought to rest.

The baling-box or press, represented at 33, constitutes one of the essential parts of this invention and is constructed in the following manner: The top panel 34 and one side panel 35 of the feed chamber are suitably hinged together at their intersection, and the side 35 is hinged to the bottom of the box in such manner that both the top 34 and side may be swung outward and be extended upon the ground in the position shown in Figs. 4 and A cable 36 is secured to the top panel 34, and after passing around suitable direction pulleys, leads to and is secured to the lever-arm 25 at a suitable point. A spring 37 is fastened to the edge of the top panel 84 and extends back to a fixed point on the ground, usually a stake, not shown, and normally tends to retain the top 34 and side 35 in their open position. A catch 38 is adapted to engage the top 34 and retain it in a closed position, while the plunger-head 15 moves forward across the feed chamber and to be released by an engagement with a lug it on the plunger 14- as soon as the head 15 has passed the feed chamber 33 and is entering the compressing chamber 38.

The operation of the invention is as follows: Power being applied to the shaft 3 through the sweep 5 in the usual manner, the cross-heads 6-16 are caused to rotate and actupon the plunger 14 and lever-arm 25, as before described. NVhen the plungerhead has just left the feed chamber and is entering the compressing box 38, the projection 14 on the plunger 11 engages a hook 39 on a line leading to the catch 38 and causes the latter to release the top panel 3-1- which is immediately opened out upon the ground, as before mentioned. Sutlicient hay or the like, to form a flake, is then placed upon the extended portions 3-t--35 while the plunger is completing its forward stroke in the compressing box 23H. lVhen the stroke of the plunger is completed, the roller T or T on the cross-head contacts the curved arm amt starts to pull back upon the plunger 1+ through the cable 26 and simultaneously lifts up the extended top 3-1 and side 37 as shown in Fig. 5, thereby gathering up the materials thereon and carrying them for- Ward, as the piston-head 15 is moved back across the feed chamber 33. As the plunger-head 15 comes to rest, clear of the feed chamber, the curved arm 25 continues on sutficiently far to completely close the top and side of the feed chamber, thus delivering the material into the baler in front 01 the plunger-head 1.3, the top 3% being then engaged by the catch 38. The spring 27 allows the arm 25 to pull the top panel 3-1 into engagement with the latch 38 irrespective of the plunger 1 1-. The materials to be compressed are now inclosed in the feed chamber 33 and in position to be acted upon by the next forward movement of the plungerhcad 15.

A shield or cover -10 extends over the feed chamber 3* as shown in Fig. 5, so as to direct the materials on the i'oldable extended portions 3-t-35 into the feed chamber.

\Vhen the plunger 15 has passed across the feed chamber 33, compressing the hay therein into the compressing box 38 as far as the cross-head (i carries it, the short. crosshead 16 acts upon the plunger and gives the already compressed body of material an additional compression, thereby forming the material in a compact flake.

From the foregoing it will be seen that the machine will be constantly at work, while in motion, the cross-heads (S1.6 bearing continuously either in carrying the plunger forward or bringing it back and delivering the materials into the feed chamber. By this arrangement the pull upon the sweep 5 is equalized, thereby making the operation of the machine easier for the draft animals.
